Abstract: 1299680 Releasable fastenings; hinges GEORG UTZ AG 30 Sept 1971 [2 Oct 1970] 45629/71 Headings E2A and E2F [Also in Division B8] A lid 2 is hinged to a box 1 by means of a pair of bearings 11, each bearing comprising a pair of lugs 12 and 13 integral with the lid and curving towards each other to embrace a hinge member 14 on the box, a spring 15 urging the lugs together to trap the member 14 within the lugs. The spring comprises a curved plate positioned in grooves 18, 19 in the lugs and having turned in ends 16 positioned in recesses 17. The box and lid may be made of a synthetic resin. The lid may have a locking bar 34 which can extend through a slot in a flange 3 in the box and can then be slid so that a hook-shaped end on the bar engages underneath the flange. Alternatively there may be a single resilient catch, or a pair of catch locks (20, Fig. 4 not shown) may depend from flange 10 of the lid through the flange 3 and can be held apart by a tang so that shoulders on the locks can engage beneath the flange 3.

IPC: G03C7/14
Abstract: 458,418. Colour photography. ST. GENIES, A. H. J. DE L., 9, Rue Neuve, Versailles, France. June 18, 1935, Nos. 17530, 17531, and 17532. Convention dates, June 19, 1934, July 7, 1934, and Sept. 20, 1934. [Class 98 (ii)] A method for copying by projection a lenticular film on to a lenticular film comprises arranging the original and copy films with their lenticulations facing the incident light emanating from at least one light source, illuminating successively the component images of the original film by the light source, projecting the component images of the original film on to the copy film successively by means of a movable aperture associated with the optical projecting system, and intercepting all light rays which have an apparent origin other than the movable aperture. As shown, three light sources S1, S2, S3 are provided behind three openings d of equal width in a wall D. Between the original film AB and the wall D is a movable screen R, having three windows e1, e2, e3, which is spaced from the film AB by a distance l corresponding to the convergence of the lenticulations of the film AB. The width of the openings d corresponds to the angular aperture of the lenticular elements of the film AB. The projection system O has a diaphragm D<1> having an aperture d<1> of width corresponding to the convergence of the lenticulations of the copy film A<1> B<1> and arranged at a distance l<1> from the film A<1>, B<1> corresponding to the angular aperture of the lenticular elements of the film A<1> B<1>. Between the diaphragm D<1> and the film A<1> B<1> is a movable screen R<1> with an aperture el. Movable opaque screens i1, i2, i3 intercept real images of the windows e1, e2, e3. The movement of the screen R may be replaced by movement of the light sources, and a common light source may be employed. In a modification a lens, which may be cylindrical or cylindrospherical, and which may be laterally moved, is arranged near the smooth side of the film AB, and to avoid consequent distortion a lens is arranged near the lenticular side of the film AB during taking, or a compensating lens .is arranged near the lenticular side of the film.

Title: Sensor circuits for electronic monitoring devices
IPC: F23N5/08
Filed: 1975-11-05
Abstract: 1480306 Condition responsive systems DANFOSS AS 5 Nov 1975 [6 Nov 1974] 45895/75 Heading G4N A sensor circuit for an electronic monitoring device, the circuit comprising a sensor 3 operative to respond to a parameter to be monitored when a predetermined D.C. voltage is applied thereto, input terminals 1, 2 for an A.C. input voltage, a Zener diode Z1 to derive the predetermined D.C. voltage from an A.C. input voltage applied to the terminals 1, 2, sensor test means comprising means in series with the Zener diode to enable a predetermined voltage increment to be selectively added to the voltage across the Zener diode for testing the sensor, the sensor being connected in parallel with the series connected Zener diode and testing means, and R-C means R1, C1, connected in series with the Zener diode 21 and the terminals 1, 2, and arranged to charge by way of the Zener diode during half cycles of one sense and to add its stored voltage to that at the terminals 1, 2 during half-cycles of the opposite sense. As shown in Fig. 1, the sensor is a gas discharge tube 3 which fires in response to U.V. radiation of a flame in a burner, flame failure resulting in de-energization of a relay 7 to cut off the fuel supply. The testing means comprises a second Zener diode Z2, an R.C. circuit R2, C2 and a switch S. In normal operation, the switch S is in the position shown and the Zener diode Z1 causes 310 V to be applied across the tube 3. A programme time switch (not shown) associated with the burner ensures that the switch S is closed for a predetermined time for testing the tube 3 before the flame is ignited. During this time the Zener diode 22 causes an additional 31V to be applied across the tube 3. If the tube firing voltage is less than the summated voltage of 341V through ageing, the tube 3 fires and the voltage across resistor R increases to above the Zener voltage of Zener diode Z4. This firing process is repeated during every other half wave so that capacitor C4 will be gradually charged until relay 7 is energized, thus indicating a faulty tube 3 and fuel ignition is prevented. If the tube 3 burns out during the test phase the relay is not energized and in the subsequent fuel ignition phase, the non-energized relay in conjunction with the programme switch is used to prevent the supply of fuel. If the tube has withstood the test, ignition takes place. In the alternative arrangement shown in Fig. 2, the Zener diode Z2 is switched into the circuit of the Zener diode Z 1 and the resistor R for testing purposes. The Zener diode Z2 in this embodiment may be replaced by another constant voltage source, Fig. 4 (not shown). In a further arrangement, Fig. 3 (not shown), the Zener diode Z2 is connected in series between the diode Z1 and the resistor R and the switch S normally short circuits the Zener diode Z2.

Abstract: 1,076,624. Automatic control of electric motors. MATERIEL ELECTRIQUE S.W. Nov.13, 1964 [Nov.15, 1963; Oct. 19, 1964], No.46314/64. Heading G3R. The acceleration of a D. C. motor, which is supplied through a rectifier-inverter, is controlled by a phase-shift circuit 6 connected to an integralproportional amplifier 7 receiving reference signal Io and signal Is representing the armature current of the motor. The signal Io is derived from proportional amplifier 8 receiving a reference signal e from amplifier 9 and speed-signal es from tachometer generator 5. The amplifier 9 has integral action, the signal e varying as a function of time, an input signal Ao being obtained from proportional amplifier 10 which compares reference signal Vo with speed-signal Vs. When the currentsignal Is exceeds a threshold value set by signal Ilo, an error signal Vs is fed back to amplifier 9 through integral-proportional amplifier 11. This adjusts the value of the signal e to a suitable initial value after the motor has been overloaded.

Abstract: 1,008,809. Coating and germinating seeds. SAATUND ERNTETECHNIK G.m.b.H. Dec. 18, 1962, No. 47746/62. Heading A2Q. Seeds, e.g. monogerm sugar-beet seeds, are coated with a composition, e.g. aqueous, comprising a substance of high molecular weight, such as peat flour or sawdust and one or more than one hydrophobic metal compound, the coating composition being oxidized to a redox potential, suitable for germination of the seeds, prior to or after the coating of the seeds. Suitable hydrophobic metal compounds are the substantially water-insoluble metal salts of higher fatty acids, such as calcium or magnesium stearate or palmitate and metal oxides, such as ferric oxide, zinc oxide, chromium oxid (Cr2 O3), red lead oxide and lead dioxide. Oxidation may be effected by hydrogen peroxide, a per-salt or a per-acid, e.g. under strongly alkaline conditions, which may be obtained by the presence of potassium or sodium silicate, and the pH of the coating may then be brought to a physiological pH, preferably between 6.5 and 8.0. Kaolin or calcium sulphate may be included in the coating composition, to give it a desired specific gravity. The coating composition may also comprise one or more of the following: a growth-promoting agent, a germination- . promoting agent, a bacterial concentrate, a seed dressing, a dyestuff, a wetting agent. Aqueous coating compositons may contain a dissolved non-electrolyte, such as cane-sugar, to raise their osmotic pressure and so prevent premature germination of seeds to which they are applied.
